CVE-2021-39683

Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to a possible out of bounds write in the copy from mbox function of sss ice util.c due to a missing bounds check. This could lead to local escalation of privilege, requiring System execution privileges. No user interaction is needed for exploitation.

Recommendations For Android kernel, consider applying a patch that includes a bounds check in the copy from mbox function to prevent out of bounds writes. As a temporary workaround, restrict access to sensitive system resources to minimize the risk of exploitation.
